TUBE FRAME EOR AXMINSTER LOOMsfk Application filed November 8, 1926. VSerial No. 146,938.

This invention relates to tube frames for .Axn'iinster looms' and it is the principal ob ject of the invention to improve upon the construction heretofore `in use to the end that the strains to which the Supporting elen'ients of the tube frame are subjected shall be reduced. A

rthe usual Anminster loom comprises av pair of spaced endless intermittently moving chains between which extend a complement ofv tube frames. .The tube frames are atl tached to the chain by means of hooks and tongues, the tongue passing ybetween the members of a double, link and the hook-eX- tending over one of the members. As heretofore constructed the chain has been located at a point not only above the tube frame bar but also above the axis of the spools, and the result of this construction is to place the entire weight of the tubey frame to one side of the supporting tongues and hooks. As the chain is transported it passes over and under yguide sprockets and it is found that as the frame passes from one side to theother of an upper sprocket the tube frame moves by gravity to assume a new position and the Strain ofl thismovement is born-e by the hook and ChaimA It is an important obj ect of our present invention to locate the chain at a point intermediate the aXis of the spools and the axis of the carrier bar of the tube frame so that the spools will have a counterbalancing effect on the carrier bar and thus reduce the strain to which the hook is subjected.

It is a further object of our invention to provide a rigid latch pivoted to the bracket of the ordinary tube frame and located to have -direct contact with the clutch of the AXminster loom.

It is a still further object of the invention to provide forV rocking the tube frames about the axis of the clutch by means so constructed as to permit the location of the transporting chainv in a position lower than has been possible under previousl constructions.

A more specific object of our invention is to provide a tube vframe bracket having an upper bearing'for the rigid hook and having the lower part thereof formed with parallel arms to enter a tubular bar, said bracket having spool vbearing vand chain engaging lwe have shown a convenient theparts moved to releasing position,

parts Secured together and .having one of the arms formed therewith.

With these and vother' objects in view `5:5 which will appearas kthe ydescription yproceeds, 'our invention resides in thecombination and arrangement of parts hereinafter described and set forth in the claims.

l Referring to Figs. 1 and 2 the'usual. pullover shaft which extends across theAXminster loom is indicated at 10 andvhas keyed thereto at each'end thereof a sprocket 11, only one sprocket being shown.v A clutch arm 12, one located at each side of the-loom, has a stud 13 tofwhich is secured a clutchv 14. By means not shown the arm 12 (shown in Fig. 2) together with the, one on the opposite side of the loom is lowered and raised each time a row of tuftsi's-to be inserted in the fabric.
